Hydraulic fracturing has been successfully applied to facilitate the large-volume production of tight oil in Canada. One critical issue following hydraulic fracturing operation is how to maximize the subsequent oil production. This research will adopt a microscopic approach for understanding how oil flow ensues after the hydraulic fracturing treatments. With the micromodels designed and built at the University of Alberta, we will explore the mechanisms that govern the oil/fracturing-fluid flow behavior at a micro scale. The proprietary fracturing fluids produced by Fusion Technologies Inc. will be comprehensively assessed in terms of their effectiveness in facilitating the oil production after hydraulic fracturing. The research results will help Fusion to improve their existing fracturing fluid recipes as well as develop new ones. Given that vast tight oil

水力压裂技术已成功应用于加拿大致密油的大批量生产。水力压裂后的一个关键问题是如何最大限度地提高后续的石油产量。这项研究将采用微观方法来了解水力压裂处理后的石油流动情况。通过艾伯塔大学设计和建造的微观模型，我们将探索在微观尺度上控制石油/压裂流体流动行为的机制。Fusion Technologies Inc.生产的专利压裂液将就其在水力压裂后促进石油生产的有效性进行全面评估。研究结果将有助于Fusion改进现有的压裂液配方，并开发新的压裂液配方。考虑到巨大的致密油
